Designer Riser TwinPack (DR-M/DR-S)


The TwinPack Designer Riser Master (DR-M)/Slave (DR-S) Vertical Stack fan coil combination is pre-piped and housed in a common cabinet assembly at the factory, shipped and installed as one unit.  TwinPacks are custom built for specific job requirements, and manufactured to the “One-Hour, Through-Penetration Fire-Stop System”.  Fire-stop must be field-furnished and meet local codes.  Drywall is installed on the face of each fan coil and thickness may be selected to meet local codes.  The TwinPack Designer Riser Master (DR-M)/Slave (DR-S) Vertical Stack combination are low-static (up to .25 ESP) fan coils with a draw-through design.  The Master (DR-M) and Slave (DR-S) are designed to be piped to a common set of risers.  Each fan coil has its own valves, controls and unique lifting brackets.  The TwinPack DR-M/DR-S cabinet is galvanized steel, 97 inches in height and insulated with ½-inch thick, over three pound density, neoprene-coated fiberglass and has unique lifting brackets.  TwinPack units have full easy access through the 36 inch return-air grilles to their separate ½-inch OD copper tube coil, easy slide-out blower/motor assembly with quick-connect plug and a galvanized steel, powder-coat epoxy drain pan covered with ⅛-inch thick insulation.  The uniquely engineered sound shield and tuning vane in the supply-air plenum provides even distribution of airflow across the grille resulting in quieter operation.  The TwinPack combination is designed for concealed applications.
